Software Usage Instructions

Select image files: Click the upload area or drag and drop images. PNG, JPG, JPEG, and WebP formats are supported, and you can select one or multiple images at a time.
Confirm the file list: After uploading, image previews and file information will be displayed. For batch files, only the first 20 previews are shown, but all files will be processed.
Set tone effects:
- Tone replacement: Unify the image with a target tone while preserving light and dark details.
- HSL adjustment: Adjust the overall image color using parameters such as hue, saturation, and brightness.
- Duotone: Set separate colors for shadows and highlights to create a duotone style.
- Grayscale, sepia, invert: Quickly create black-and-white, vintage, or negative effects.
Adjust detail parameters: You can set parameters such as effect strength, hue rotation, saturation, brightness, contrast, gamma, color temperature, and tint, and quickly apply common styles using presets.
Set output options: You can choose to keep the original format or output as PNG, JPEG, or WebP, and set JPEG/WebP quality. For transparent PNGs, you can choose to preserve the alpha channel or convert it to a white background.
Save common settings: Click “Save Settings” to save the current parameters, making it easy to reuse the same color grading scheme later.
Process and download: Click “Start Processing Images” to generate the results. A single image can be downloaded directly, while multiple images will be packaged as a ZIP. Output file names match the original file names by default, and duplicate names will automatically have numbers appended.

FAQ

A: Tone replacement is suitable for icons, illustrations, product images, avatars, material images, and other images that need a unified color style. It takes the brightness levels of the original image into account, rather than simply overlaying a solid color.

A: HSL adjustment mainly changes the original image’s own hue, saturation, and brightness; tone replacement maps the image to a specified target color, making it more suitable for creating a unified brand color or visual style.

A: The alpha channel is preserved by default, which is suitable for assets such as icons, logos, and stickers. If you need an image with a white background, you can check “Convert transparent areas to white background”.

A: The original file names are kept by default. If multiple exported files have the same name, the tool will append a number to the file name to avoid overwriting results with the same name.

A: PNG is suitable for transparent backgrounds, icons, and images that need crisp edges; JPEG is suitable for photo-like images; WebP is suitable for balancing image quality and file size. If you're not sure, you can choose to keep the original format.

A: A large number of images or large image dimensions will use more memory. We recommend processing very large images in batches and confirming the output format and quality settings before processing to avoid repeated generation.
